Dear all.
I am trying to build current sensor module which can measure or sensor range 1~2A. Intially i tried with off shelf product ACS712 Module. But i found they are more distortion at output. Output are not stable. Inspite of building filter or by software i could not able to maintain accuracy to 1%.
These model i already tried
www.sparkfun.com/products/8882
www.sparkfun.com/products/8883
My specification
current sensing range :1~2A
analog output: 0~5v Dc
accuracy :1 %
arduino Board for Programming.
http://openenergymonitor.org/emon/buildingblocks/dc-shunt
Now i am planning to use above circuit for sensing. is anybody suggest me view of designing it. Is any other method i can more accurate analog output.
For me more important accuracy and produce analog output.
I am planning to use below sensor with Lm393 amplification . I don't how to amplify the circuit here.

i dont know why they using it??
